The astronomical education and public outreach (EPO) community plays a key role in conveying the results of scientific research to the general public. A key product of EPO development is a variety of non-scientific public image resources, both derived from scientific observations and created as artistic visualizations of scientific results. This refers to general image formats such as JPEG, TIFF, PNG, GIF, not scientific FITS datasets. Such resources are currently scattered across the internet in a variety of galleries and archives, but are not searchable in any coherent or unified way.
Just as Virtual Observatory standards open up all data archives to a common query engine, the EPO community will benefit greatly from a similar mechanism for image search and retrieval.
A new standard has been developed for astronomical imagery defining a common set of content fields suited for the needs of astronomical visualizations. This encompasses images derived from data, artist's conceptions, simulations, photography, and can be ultimately extensible to video products.
The first generation of tools are now available to tag images with this metadata, which can be embedded with the image file using an XML-based format that functions similarly to a FITS header. As image collections are processed to include astronomy visualization metadata tags, extensive information providing educational context, credits, data sources, and even coordinate information will be readily accessible for uses spanning casual browsing, publication, and interactive media systems.
